EDWARD WIARD, OF LOUISVILLE, KENTUCKY, ASSIGNOR TO BENJAMIN F.

' AVERY, OF SAME PLACE.

IMPROVEMENT IN PlLOWS.

Specification forming part of Letters Patent N o. 117,024, dated July11, 1871.

To all whohzl it may concern:

Be it known that I, EDWARD WIARD, of Louisville, in the county ofJeii'erson and State of Kentucky, have invented a new and Improved Plow;and I do hereby declare that the followin g is a full, clear, and exactdescription thereof, rei'- erence being had to the accompanying drawingmaking a part of this specification, in which- Figure l is a perspectiveview oil my improved plow. Fig. 2 is a perspective view ofthe standardand land-side plate. Fig. 3 is a perspective view of the standard, theland-side plate, and the skeleton support for the share and moldboard.Fig. 4 is a perspective view of the combined point and share.

Similar letters of reference indicate corresponding parts in the severalligures.

This invention relates to certain novel improvements on the constructionof turn-plows; and consists: lst, in a wrought-iron standard andwrought-iron land-side, welded together and adapted for separate lightpoints. 2d, in a skeleton frame adapted for iirmly uniting the point andmold-board to the land-side and standard in a very substantial manner,and also aii'ording a means `for securing in place the mold-boardhandle, as will be hereinafter explained.

To enable others skilled in the art to understand my invention, I willexplain its construction and operation.

In the accompanying drawing, A represents a wrought-iron standard, whichis concave in front, convex behind, and extended forward at its lowerend into a point, a, which is perforated transversely at b and b3. B isthe land-side, which is made of wrought-iron, of proper thickness,length, and width, beveled at c, and iirmly welded to the standard A soas to lap over the same, as shown in Fig. 2. The standard and land-sidethus form a single piece, having' a vertical shoulder at g, of athickness corresponding to the thickness of the land-side portion B ofthe standard and the land-side portion D of the share or point D. Grepresents a skeleton frame, which is made of wrought metal or ofmalleable cast metal, pressed into proper shape to receive upon it andafford substantial though a very light bed for the mold-board O. Thisframe G is constructed with lugs or lips o, 19', p, p, and 1L a on itsedges, as shown in Fig. 3. The lugs 0, p', a, and n receive boltsthrough them for securing the frame to the standard and land-side, andalso for securing the share D and mold-board C to the frame. The lugs pp, which are bent downward from the mold-board, receive bolts throughthem, which secure the mold-board handle to the said frame. In Fig. 3the perforations t' 'i receive through them the bolts which are used tosecure the mold-board O to the frame G. The share D, with its pointedend and its land-side portion D', is secured by bolts to the frame-lug pand to the tapering point a of the standard A. All of the bolts whoseends are exposed on the outer sides ofthe plow are countersunk into themetal so as not to leave raised surfaces. V

It will be seen from the above description, Fig. l, that when the pointor share is secured in its place the rear end of the land-side portion Dof this share lits snugly against the shoulder at g, and leaves theexternal surfaces flush, while the extended portion c of the standard Aai'ords a firm support, both laterally and vertically, for the share.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, 1s-

1. The standard A with extended support a and with land-side B unitedthereto and terminating at g, leaving a shoulder for the plow-point D',substantially as and for the purpose set forth.

2. The frame G, constructed with lugs p19, bent and adapted to receivethrough them bolts which secure the mold-board handles to the plow,substantially as described.
